Virtually none – however the same day, the eyelids can swell a little in some people, and appear puffy, and the eyes can sometimes have minor redness. Usually within a few hours, this will resolve and your eyes and eye area will look relatively normal – it will just appear as though you have slightly thicker liquid eyeliner on (the line shrinks as swelling dissipates).  

Healing is very fast for eyeliner, normally within a couple of weeks. A very small amount of dry skin may shed from the eyelid around day 3-7, and the eyelids may need a little tight or dry during this time, but time off from work or social events past the day of the treatment is not normally required.
